Cardamom seed bioactives: A review of agronomic factors, preparation, extraction and formulation methods based on emerging technologies to maximize spice aroma economic value and applications.

Cardamom seed (Elettaria cardamomum (L.)) is a well-appreciated spice in food and pharmaceutical industries owing to its unique rich flavor dominated by oxygenated monoterpenoids, α-terpinyl acetate and 1,8-cineole, to which most of the quality of cardamom essential oil (CEO) is attributed. CEO output is greatly influenced by different agronomic factors, processing, and EO extraction methods. In that context, the goal of this study is to provide an overarching review regarding emerged technologies along with their optimization parameters to achieve optimal oil yield with the best flavor quality. Furthermore, the recent approaches employed in CEO stabilization were highlighted alongside their pharmaceutical and food applications. Moreover, the different aspects of superlative CEO production including agricultural aspects, climatic requirements, and processing methods were also explained.
